Nitro Image/GIF Profile Badge Perk

Another Nitro profile perk, alongside banners, can include badges next to names that users can set. These badges take the form of an image placed next to someone's name, and is visible in DMs. The concept is similar to role badges, but for people, and only visible in DMs.

This will be visible next to a profile in a DM list and also while chatting in private messages

Alternatively, you could make this a default option for all people and give the animated option to Nitro users.
